Megalith - from the Greek Mega = huge and lith = stone
Single standing stones and rings - standing silent sentinel in remote parts of the British Isles in tribute to their builders from long ago. For thousands of years they have waited - over a hundred generations of mankind. What did they mean, why were they constructed - we do not know. Some of their very attraction is that these reminders of the dawn of Man are mute, no writing and very little imagery or art has been passed through the millennia from these ancestors. Visitors wonder, but the stones hold their secrets, and maybe they will hold their mystery for ever. Archaeologists infer that they were ceremonial or ritual sites, simply from the sheer collective effort needed to raise them. Too many sites which hold human remains seem to be called burial chambers. Such logic might, in thousands of years time look at churches which often contain human remains and sarcophagi and conclude that the cathedrals of Europe were grand burial chambers too... Maybe it is better to say we do not know.
I have listed these sites in their attractiveness to the visitor new to megaliths. You can expand the listing to show all sites pictured here, and to find other sites the Stone Search lists far more megaliths than I have on this site.
